...the following example. A[i] = 42; // S1 if( condition ) // C1 { A[i] = 20; // S2 } B[i] = A[i]; // S3 Testing for all pairs would indicate that there exists a WAR between S2 and S3 but it is only correct if C1 evaluates to true. Similarly, there may or may not be a WAW between S1 and S2. Thus to clearly indicate the possible paths I would like to generate something like: C1 (true) : WAW - S2->S1 , RAW - S3->S2 C1 (false) : WAW - S3->S1 So then it seems to me that building the dependence graph is essential. Are there no other Analysis/Transforms which...

Hello llvm-dev, I'm currently integrating an experimental instruction scheduler into LLVM and have come upon a point of confusion regarding WAW dependencies. I apologize in advance for the unnecessarily convoluted example, but it's one solid case which fails on my scheduler and where I can get LLVM to produce a graph that shows my question clearly. I have a small piece of code like this which I'm compiling for x86-64 with -O3: --...

For our helpdesk application, we need record full conversation between any caller and one or two helpdek numbers (while the conversation is running). After conversation is ended (hangup ..), the recorded file (WAW) is putted into database. Using AGI, record and put to database is OK, but only as exclusive task. But I need record WAW file "in background" the standard conversation. Is any vay to do it with Asterisk ? Thanks.

...nformation I require (based on a prior AliasAnalysis pass), however I need to pass the Src and Dst instructions in program order. I was wondering how I can collect all the memory access pairs from the basic blocks within the CFG of the loop body which would allow me to know which pairs are RAW/WAR/WAW. It seems related to the approach outlined here : https://sites.google.com/site/parallelizationforllvm/building-the-dependence-graph Is there any existing implementation I can take a look at? It seems that the only the DependenceAnalysis::depends is only called in the dumpExampleDependence() funct...

Hi Sebastian, Recently, I found the "Polly - Calculate dependences" pass would lead to significant compile-time overhead when compiling some loop-intensive source code. Tobias told me you found similar problem as follows: http://llvm.org/bugs/show_bug.cgi?id=14240 My evaluation shows that "Polly - Calculate dependences" pass consumes 96.4% of total compile-time overhead

Hello all, My set up is a fractionated t1, with 1-6 voice channels, 21-24 data channels. I have a t100P installed in a amd 1500 with 512meg. Question: In order to set up the data channels, is the following correct? 1) compile new kernel with generic hdlc support 2) compile hdlc from hq.pm.waw.pl/hdlc 3) uncomment KFLAGS+=DConfig_ZAPATA_NET in zaptel makefile 4) compile zaptel, 5 compile rest of asterisk 6) add following to zaptel.conf span=1,0,0,esf,b8zs e&m=1-6 nethdlc=21-24 7) sethdlc hdlc0 hdlc_net (I know there is supposed to be a parity and another setting, but bugger if I...
